BACKGROUND OF THE INVENTION

(a) Field of the Invention

The present invention relates to an up-and-down swing mechanism for separated heald frames of a sample fabrics machine, and more particularly to a mechanism able to automatically control a portion of heald frames of a sample fabrics machine, and suspend up and down swinging according to the style of sample fabric to be produced.

(b) Description of the Prior Art

The rapid development in science and technology has brought about a certain degree of improvement in the quality of life of people, correspondingly, clothing material has tended towards diversification, faster discarding of the old for new, increasing difficulty to pin down demands of different groups of people, and the differentiation between age groups is also becoming more and more indistinct. Under such factors, textile mills (especially those which provide design capability) are all equipped with sample fabrics machines, which are used for design and sample work before mass production of fabrics.

Sample fabrics machines of the prior art disclose: a base; a plurality of heald frames, the heald frames being installed on the base using separated means, and the heald frames are provided with a plurality of healds, each of the healds being formed with a heald eye, warp threads respectively serially pass through the heald eyes, and different heights between the heald frames are used to separate out a shuttle path between the designated warp threads; a rapier tape chuck, which is provided with a crook, the rapier tape chuck moves back and forth in the shuttle paths, and is used to intercalate cut-off weft thread between the warp threads through the shuttle paths; a color selector device, which is used to feed the designated weft thread to an established region, and clutching of the weft thread of the established region by the rapier tape chuck is used to intercalate the weft thread, after being cut-off, between the warp threads through the shuttle paths; a weft cutting device, which moves back and forth in the established region, the weft cutting device being used to implement cutting of the clutched weft thread carried by the rapier tape chuck through the established region; a steel reed, which is pin connected to the base, the steel reed being provided with a plurality of reeds, the warp threads pass through between the reeds, and the steel reed is used to push the clutched weft thread carried by the rapier tape chuck in the direction of the shuttle path, thereby causing the weft threads passing between the warp threads to be mutually contiguous with each other.

However, although the sample fabrics machines of the prior art are able to automatically weave sample fabrics, nevertheless, the heald frames use pneumatic cylinders to push upwards and downwards to effect up and down swinging, and the pneumatic cylinders using gas thrust as its power source results in slow movement response of the up and down swinging of the heald frames. Hence, the up and down strokes cannot be finely adjusted, making fine control difficult. Moreover, gas thrust produces a large amount of noise, and is thus considerably inconvenient in use.

SUMMARY OF THE INVENTION

Hence, in light of the shortcomings of the aforementioned prior art, the inventor of the present invention, having accumulated knowhow and manufacturing experience of a diverse range of sample fabrics machines, attentively researched various methods to resolve the shortcomings, which, following continuous research and improvements, culminated in the design of a completely new up-and-down swing mechanism for separated heald frames of a sample fabrics machine.

The objective of the present invention is to provide an up-and-down swing mechanism for separated heald frames of a sample fabrics machine able to suspend up and down swinging of a portion of heald frames using separated means.

According to the aforementioned objective, the up-and-down swing mechanism for separated heald frames of a sample fabrics machine comprises a plurality of regular arranged heald frames fitted to a sample fabrics machine, wherein a lower end each of the heald frames is connect to a fixed plate, and transmission arms are respectively pivotal located on two sides of a lower end of each of the fixed plates. A master drive and a slave drive are respectively fitted within the sample fabrics machine corresponding to positions of the two transmission arms. The master drive is driven by a power device (such as: a servomotor), a swing arm is pivotal located to the master drive, and a clutch is located between the power device and the swing arm, thereby enabling the clutch to engage with the swing arm or separate from the swing arm to cause up and down swing or no swing thereof. Another swing arm is fitted to the slave drive, and semicircular rows of teeth are respectively located on corresponding ends of the two swing arms. The two rows of teeth are disposed to mutually engage, thus, when the swing arm swings, the other swing arm is actuated and swings in synchronization therewith. Furthermore, the upper end of one of the transmission arms is pin connected to one side of the lower end of the fixed plate, and the lower end is pin connected to the other end of the swing arm relative to the row of teeth, while the upper end of the other transmission arm is pin connected to the other side of the lower end of the fixed plate, and the lower end is pin connected to the other end of the other swing arm relative to the row of teeth. When in use, according to the style of sample fabric to be produced, controlling a portion of the clutches to engage or separate from the swing arms causes the two swing arms to swing or not swing, which then drives a portion of the heald frames to cause up and down swing or no swing thereof through the two transmission arms, thereby weaving the required style of fabric.

To enable a further understanding of said objectives and the technological methods of the invention herein, a brief description of the drawings is provided below followed by a detailed description of the preferred embodiments.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention relates to an up-and-down swing mechanism for separated heald frames of a sample fabrics machine. Referring to FIGS. 1, 2 and 3, which show an up-and-down swing mechanism for separated heald frames of a sample fabrics machine of the present invention, wherein a plurality of regularly arranged heald frames 11 are fitted to a sample fabrics machine 10, a lower end of each of the heald frames 11 is connected to a fixed plate 12, and transmission arms 13, 14 are respectively pivotal located on two sides of a lower end of each of the fixed plates 12.

A master drive 21 and a slave drive 22 are respectively fitted within the sample fabrics machine 10 corresponding to positions of the two transmission arms 13, 14. The master drive 21 is driven by a power device (such as: a servomotor) (not shown in the drawings), a swing arm 211 is pivotal located to the master drive 21, and a clutch 23 is located between the power device and the swing arm 211, thereby enabling the clutch 23 to engage with the swing arm 211 or separate from the swing arm 211 to produce up and down swing or no swing thereof.

Another swing arm 221 is fitted to the slave drive 22, and semicircular rows of teeth 213, 223 are located on corresponding ends of the two swing arms 211, 221 respectively. The two rows of teeth 213, 223 are disposed to mutually engage, thus, when the swing arm 211 swings, the other swing arm 221 is actuated and swings in synchronization therewith. Furthermore, the upper end of the transmission arm 13 is pin connected to one side of the lower end of the fixed plate 12, and the lower end is pin connected to the other end of the swing arm 211 relative to the row of teeth 213, while the upper end of the other transmission arm 14 is pin connected to the other side of the lower end of the fixed plate 12, and the lower end is pin connected to the other end of the other swing arm 221 relative to the row of teeth 223.

Hence, according to the style of sample fabric to be produced, controlling a portion of the clutches 23 to engage or separate from the swing arms 211 within a period of time (as depicted in FIGS. 2, 4) causes the two swing arms 211, 221 to swing or not swing, which then drives a portion of the heald frames 11 to cause up and down swing or no swing thereof through the two transmission arms 13, 14 within a period of time, thereby weaving the required style of fabric.

Referring again to FIGS. 1, 2 and 3 together with FIG. 4, each of the clutches 23 is connected to the power device, thereby enabling the power device to drive each of the clutches 23 in synchronous rotation. A protruding piece 231 is located on each of the clutches 23, a circular arc-shaped fixed plate 215 is pivotal located on the swing arms 211 corresponding to the positions of the protruding pieces 231, and a clasp groove 216 is provided on an inner side of the fixed plates 215 to correspond with the protruding pieces 231, thereby enabling the protruding pieces 231 to insert into the clasp grooves 216. Hence, when the power device drives the clutches 23 to effect synchronous rotation thereof, then the protruding pieces 231 inserting into the clasp grooves 216 enable the power device to indirectly drive the swing arms 211 and cause up and down swing thereof.

Referring again to FIGS. 1, 2, 3 and 4, a selector 15 is located on the sample fabrics machine 10 corresponding to the position of the fixed plate 215 of each of the swing arms 211, and a push rod 151 is located on each of the selectors 15 above each of the fixed plates 215. The selectors 15 are electrically connected to a control circuit (not shown in the drawings) of the sample fabrics machine 10, and the selectors 15 are controlled by the circuit control, thereby enabling the control circuit to control the selectors 15 to extend downward a portion of the push rods 151 within a period of time according to a set program, and thus cause the push rods 151 to actuate and move the fixed plates 215 and induce the protruding pieces 231 of the clutches 23 to separate from the clasp grooves 216 of the fixed plates 215, thereby causing the clutches 23 to run idle and be unable to drive the swing arms 211 and effect up and down swing thereof, which causes the swing arms 211 to stop swinging within that period of time, and simultaneously suspends up and down swinging of the corresponding heald frames 11. Accordingly, controlling suspension of up and down swinging of a portion of the heald frames 11 is used to enable the required fabric to be woven.

In conclusion, the up-and-down swing mechanism for separated heald frames of a sample fabrics machine of the present invention is assuredly provided with an innovative structure not found in the prior art. Moreover, no similar products have been seen in any publication or in the market; the present invention is thus provided with undoubted originality.
